    Sun, wind and wave-powered: Europe unites to build renewable energy 'supergrid'
    Alok Jha, 3 January 2010 (UK Guardian)

    "[The EU Supergrid] would connect turbines off the wind-lashed north coast of Scotland with Germany's vast arrays of solar panels, and join the power of waves crashing on to the Belgian and Danish coasts with the hydro-electric dams nestled in Norway's fjords: Europe's first electricity grid dedicated to renewable power will become a political reality [in 2010]…as nine countries formally draw up plans to link their clean energy projects around the North Sea.

    "The network, made up of thousands of kilometres of highly efficient undersea cables that could cost up to €30bn (£26.5bn), would solve one of the biggest criticisms faced by renewable power – that unpredictable weather means it is unreliable…With a renewables supergrid, electricity can be supplied across the continent from wherever the wind is blowing, the sun is shining or the waves are crashing…By autumn, the nine governments involved – Germany, France, Belgium, the Netherlands, Luxembourg, Denmark, Sweden and Ireland and the UK – hope to have a plan to begin building a high-voltage direct current network within the next decade. It will be an important step in achieving the European Union's pledge that, by 2020, 20% of its energy will come from renewable sources…"

    "More than 100GW of offshore wind projects are under development in Europe, around 10% of the EU's electricity demand, and equivalent to about 100 large coal-fired plants. The surge in wind power means the continent's grid needs to be adapted…[A European Wind Energy Association (EWEA)] study last year outlined where these cables might be built and this is likely to be a starting point for the discussions by the nine countries…Renewable energy is much more decentralised and is often built in inhospitable places, far from cities. A supergrid in the North Sea would enable a secure and reliable energy supply from renewables by balancing power across the continent…Norway's hydro plants – equivalent to about 30 large coal-fired power stations – could use excess power to pump water uphill, ready to let it rush down again, generating electricity, when demand is high…

    "The European Commission has also been studying proposals for a renewable-electricity grid in the North Sea. A working group in the EC's energy department…will produce a plan by the end of 2010…The cost of a North Sea grid has not yet been calculated, but a study by Greenpeace in 2008 put the price of building a similar grid by 2025 at €15bn-€20bn. This would provide more than 6,000km of cable around the region. The EWEA's 2009 study suggested the costs of connecting the proposed 100GW wind farms and building interconnectors, into which further wind and wave power farms could be plugged in future, would probably push the bill closer to €30bn. The technical, planning, legal and environmental issues will be discussed at the meeting of the nine this month…"


    Eventually, Supergrid can connect with Desertec and integrate a wide spectrum of New Energies. (click to enlarge)

    "This supergrid, which has support from scientists at the commission's Institute for Energy (IE), and political backing from both the French president, Nicolas Sarkozy, and Gordon Brown, would link huge solar farms in southern Europe – producing electricity either through photovoltaic cells, or by concentrating the sun's heat to boil water and drive turbines – with marine, geothermal and wind projects elsewhere on the continent. Scientists at the IE have estimated it would require the capture of just 0.3% of the light falling on the Sahara and the deserts of the Middle East to meet all Europe's energy needs.

    "In this grid, electricity would be transmitted along high voltage direct current cables. These are more expensive than traditional alternating-current cables, but they lose less energy over long distances…[Supergrid] could link into grids proposed for a much larger German-led plan for renewables called the Desertec Industrial Initiative (DII). This aims to provide 15% of Europe's electricity by 2050 or earlier…[L]aunched last November with partners including Munich Re, the world's biggest reinsurer, and some of Germany's biggest engineering and power companies…[DII would invest in a] $400bn (£240bn) plan to use concentrated solar power (CSP) in southern Europe and northern Africa…[and build trans-Mediterranean transmission]…"
